Wheel Lock Nuts for Car Security / Anti Theft Nut

Wheel Lock Nuts for Car Security / Anti-Theft Nut We offer a wide range of nuts made from low carbon steel (mild steel), medium carbon steel, alloy steel, stainless steel, brass, and aluminum alloys. To meet different requirements for corrosion resistance or strength, our nuts can be further treated with various surface finishes such as heat treatment, black oxide, zinc coating, hot-dip galvanizing, black zinc, brass plating, nickel and chrome plating, dacomate, and more. Please specify your requirements when placing an inquiry. A nyloc nut, also known as a nylon insert lock nut, polymer insert lock nut, or elastic stop nut, is a type of locking nut. It features a nylon collar insert that prevents the nut from loosening. These nuts are commonly referred to as "nylok" or "nylock." The plastic insert is positioned at the end of the nut and has an inner diameter slightly smaller than the major diameter of the screw. As the nut is tightened, the insert deforms elastically over the threads, creating a compressive force that locks the nut in place. Nyloc nuts maintain their locking ability up to 250°F (121°C). There is some debate on whether nyloc nuts can be reused. For example, according to *Carroll Smith's Nuts, Bolts, Fasteners, and Plumbing Handbook*, the nylon insert is not damaged during installation and can be reused multiple times. However, the Federal Aviation Administration allows reuse only if the prevailing torque is within specification. On the other hand, some military specifications require replacement of self-locking nuts in critical areas. Various aerospace-grade specifications also require maintaining running torque after multiple assembly cycles without preloading the fastener. Below is a detailed product table:
